I was thinking more locally than global.
I own 9 generators, mostly older units made between 1945 and 1990.
The unloved surplus units I save rag and bone men.
They generally are everywhere if you look.
I don't think its a bad idea for everyone to have some basic stuff.
A spare sump pump and some hose, a generator, a basic supply of home consumables like dried pasta canned corn frozen peas and ground beast in the freezer.
You should have a can of nuts and bolts, a jug of motor oil, zip ties, spare tarps a wheel barrow and shovels...
Calking gun, duct tape, wd40 and vice grips....
